Analysis and treatment of large-scale nuclear heating commissioning problems

Abstract

Through the modification of a nuclear power plant, the extraction steam on the exhaust pipe of the high-pressure cylinder of the steam turbine is used to heat the circulating water of the heat network, and the pressurized anf heated circulating water of the heat network is supplied to the secondary thermal power station, and then supplied to various users after heat exchange, realizing the first large-scale nuclear heating in China. This paper introduces the function and process of nuclear heating system, and focuses on the analysis of the problems in the commissioning process, which provides a reference for the commissioning of other domestic nuclear power plants after nuclear heating modification.
